Could I ever get a blue roan?

Hi all. I have another thread on here discussing my mares genes :) She is registered as a chestnut roan. Although if she is truly a roan, she is minimally expressed. I plan to get her genetically tested one day. Just out of curiosity, would it be possible to get a blue roan out of her? What would you have to breed to get a blue roan (that's my biggest question.) This is only a curiosity thread. Nothing serious. She has only been bred once and had a pali, sire was a pali. Any ideas would be great :)

Depends on her agouti status. If she is carrying two copies of bay, then no matter what you do, she will never have a black foal. However, if she only has one, or no, agouti genes, then she could very well have a black foal, which is the base of a blue roan.

Mods, grant me the serenity to see the opinions I cannot change, courage to change the ones that should change, and the wisdom to spot the trolls.

Help with color questions!!

Here is the link to the first one. Chiilaa, I think you were the one who originally helped me solve this delema :) But now that I went back to look, I actually am confused...I think they may have changed the color of the mare you thought was a roan...now it says "blk ov"...but when you got to her info, all you see is viagra info??? Lmbo!!! I'll have to look on her dams side and see how far back any bays are. Would I have to breed her to a blue roan?

If she has NO agouti, and you breed her to an E/E stud, then you are probably going to get a black. You don't know her agouti status or zygosity of the roan, so no telling. You can get her tested for this, though.

Do you have a full body picture of your mare? I tried looking in your "Barn" to see a picture of her, but the ones that show her full body are too far away or too dark to tell if she may or may not be a roan at all.

If she isn't a roan, you could still get one if you bred her to a homozygous black, homozygous roan stallion. Provided she isn't carrying agouti, anyway, which would give you a 50% of bay roan if she is heterozygous and a 100% of bay roan if she's homozygous.

On the link to the original thread, there are pictures of her that show a closer view of her coat.
So what would someone have to breed to get a blue roan? A blue roan to...?

You would have to know her agouti status first, to know if she can even produce a black.

Your best bet would breed her to a EE RnRn stallion.

UC Davis has a $25 test to see if she has Agouti or not. Horse Tests

Agouti restricts black, but since you have a red horse, it is impossible to know whether she is carrying it or not since she has no black to restrict.

thank you all!!! Does anyone know of a stud who carries those genes?
I'll bet it costs an arm and a leg to breed to one!! Lol
